How Do Solar + Battery Help?

Solar + Battery = Financial Freedom & Energy Security

Solar eliminates your electric bill. Battery storage protects your home. Together, they deliver complete energy independence.

Eliminate Your PECO Bill

A properly sized solar system offsets 80-100% of your electric bill. PECO's 1:1 net metering credits you at the full retail rate ($0.22/kWh) for every kWh you export.

How net metering works

Earn SREC Income

Pennsylvania pays you for every 1,000 kWh your system produces. A typical 10 kW system earns $200-$300 per year in SREC income on top of your bill savings.

How PA SRECs work

Never Lose Power

Battery backup keeps your lights, fridge, internet, and HVAC running during grid outages. Solar recharges your batteries daily for potentially unlimited backup duration.

Protect Against Rate Hikes

Solar can reduce or eliminate your electric bill for 25+ years. Every time PECO raises rates, your savings increase. Solar is a hedge against utility inflation.

What Happens When the Grid Goes Down?

When the Grid Goes Down, Your Home Stays On.

Power outages are becoming more frequent and lasting longer across Southeastern PA. A solar + battery system means you never have to worry about losing power again. Your solar panels recharge your batteries every day, providing clean, quiet, unlimited backup — unlike a gas generator that runs out of fuel.

Whole-Home Backup

Keep everything running — lights, HVAC, refrigerator, internet, medical equipment, and more.

Solar-Recharged Daily

Your batteries recharge from solar every day, providing potentially unlimited outage protection.

Silent & Clean

No noise, no fumes, no fuel runs. Battery backup is automatic, instant, and maintenance-free.

Storm-Ready

Pre-charge your batteries before severe weather. Smart systems detect incoming storms automatically.

New for 2026

V2X Bidirectional EV Charging

Your EV battery is 5–7x larger than a home Powerwall. With Sigenergy's V2X charger, your EV becomes a massive backup power source — enough to run your home for 2-4 days.

Rated 5.0 from 27 reviews on Google

My PECO bill went from $280/month to virtually nothing. The SREC income is an added bonus I didn't expect. Mike walked me through the entire ROI — it was a no-brainer financially.

Sarah M.

Penn Valley, Montgomery County, PA

We got Tesla Powerwalls along with our solar panels. When our neighborhood lost power for 36 hours last summer, our house never blinked. The peace of mind alone is worth the investment.

David R.

Haverford, Delaware County, PA

Between eliminating our $3,200/year PECO bill and earning SREC income, our system is paying for itself faster than projected. And knowing we have battery backup for outages — priceless.

Common Questions

Solar Savings & Battery Backup FAQ

Everything Southeastern PA homeowners need to know about solar economics and grid resilience.

In Southeastern PA, solar panel installation typically costs between $2.50 and $3.00 per watt before incentives. A small 5 kW system costs approximately $15,000, and a more typical 10 kW residential system averages about $26,500 before incentives. Pennsylvania homeowners also earn income through the PA SREC (Solar Renewable Energy Certificate) program, which further reduces the effective cost. With PECO's 1:1 net metering and SREC income, the economics are compelling. 100% financing is available with $0 down.
The typical payback period for a grid-tied solar system in Southeastern Pennsylvania is 8 to 10 years. This factors in Pennsylvania SREC income (currently worth approximately $15-$25 per SREC) and PECO's 1:1 net metering program, which credits you at the full retail rate for excess electricity sent to the grid. After payback, your solar system generates tax-free savings for another 15-20+ years.
Most homeowners in Southeastern PA can offset 80-100% of their PECO electric bill with a properly sized solar system. With PECO rates at $0.22/kWh and rising, a typical 10 kW system saves $2,500-$3,500+ per year on electricity alone. Add PA SREC income on top of that, and you're looking at even stronger returns. Over 25 years, total savings often exceed $80,000-$100,000.
Solar panels alone will shut down during a grid outage for safety reasons. However, when paired with a battery storage system like Tesla Powerwall, Enphase, or Sol-Ark, your solar panels will continue to charge your batteries and power your home even when the grid is down. We offer both whole-home and essential-load backup configurations, so your lights, refrigerator, internet, medical equipment, and HVAC stay running through any outage.
Grid reliability has declined significantly across Southeastern PA and the broader PJM Interconnection region. Severe weather events, aging infrastructure, and increased demand are causing more frequent and longer outages. Battery storage gives you energy independence — your home keeps running regardless of what happens on the grid. Many homeowners also use batteries for time-of-use arbitrage, storing cheap solar energy during the day and using it during expensive peak hours.
We are certified installers of Tesla Powerwall, Enphase IQ batteries, Sol-Ark, EG4, Sigenergy, FranklinWH, and Fortress battery systems. Each brand has different strengths — Tesla Powerwall is great for seamless whole-home backup, Enphase offers modular scalability, and Sol-Ark provides powerful hybrid inverter solutions. We help you choose the right system based on your backup needs, budget, and whether you want whole-home or critical-load coverage.
Net metering allows PECO customers to send excess solar electricity back to the grid and receive a credit on their bill at the full retail rate. Pennsylvania offers 1:1 net metering, meaning every kilowatt-hour you export is worth the same as every kilowatt-hour you consume. Credits roll over month to month, so your summer overproduction offsets your winter bills. Important: PECO performs an annual true-up on May 31st — any remaining excess credits are cashed out at the energy-only rate (excluding delivery and transmission), so proper system sizing matters.
SRECs (Solar Renewable Energy Certificates) are credits generated for every 1,000 kWh (1 MWh) your solar system produces. In Pennsylvania, electric utilities are required to purchase SRECs to meet renewable energy mandates, creating a market where homeowners can sell their SRECs for additional income. A typical 10 kW residential system generates about 12 SRECs per year. SREC prices fluctuate but currently trade in the $15-$25 range in the PA market.
Yes. We offer 100% financing with $0 down, so you can start saving on your electric bill immediately without a large upfront payment. In many cases, your monthly loan payment is less than what you were paying PECO — meaning you save money from Day 1. We'll walk you through all financing options during your free consultation to find the best fit for your budget.
